According to Deadline, Morgan “reached the status of Comandante, the sole foreigner other than Argentinian Che Guevara to be so highly regarded. Shortly after, Morgan, a shadowy man whose motives for being there were subject to suspicion, was imprisoned and facing a firing squad, charged with working for U.S. intelligence. At the same time, his exploits as a rebel soldier led J. Edgar Hoover and everyone else scrambling to sort out his motives and who he was working for.”
Clooney is attached to direct the project though it’s currently unknown whether he’ll also be taking the role of Morgan as well. I’m sure we’ll hear all sorts of casting news soon enough.
